  • Patent number: 10024983
    Abstract: Exemplary embodiments of several new metal-loaded plastic scintillators are reported herein, comprising sterically and electronically isolated organotin additive complexes. Distance-dependent quenching relationships have been used as design criteria for the selection and synthesis of these organometallic additives, resulting in increased light yields and improved gamma-ray energy resolution values relative to previously reported PS/PVT examples. Fast scintillation decay properties have also been characterized in the prepared scintillators, rivaling the kinetics of stilbene-doped bibenzyl and BC-422Q-1% while providing higher light yields than these reference materials.

  • Patent number: 7312564
    Abstract: A cathode ray tube has an electron gun oriented along an axis (Z), comprising a quadrupolar device which comprises three electrodes (5, 6, 7). Each electrode possesses a central aperture, a right lateral aperture and a left lateral aperture all three substantially rectangular. The centers (c5.1, c7.1) of the central apertures of the three electrodes are aligned along the axis (Z) of the gun. The centers (c6.1, c6.3) of the left and right lateral apertures of the second electrode (6) are situated along respectively a first axis (z1) and a second axis (z3) that are parallel to the axis (Z) of the gun. The centers (c5.1, c7.1) of the left and right lateral apertures (5.1, 5.3, 7.1, 7.3) of the first and/or of the third electrode (5,7) are offset with respect to the axes (z1, z3) passing through the centers of the apertures of the second electrode. Such an arrangement makes it possible to correct the MODEC defects.

  • Publication number: 20050253499
    Abstract: The invention relates to a main electron lens for an in-line electron gun, comprising a first, focusing electrode and a second, accelerating electrode which are equipped with optical plates, each provided with a central hole and with two outer holes. The first optical plate is placed at a first distance from the aperture of the first electrode and the second optical plate is placed at a second distance from the aperture of the second electrode. The ratio of the first and second distances is determined by the formula: L1/L2=A11(?Vd)2+A1?Vd+A0+C0×Bias in which: A11, A1, A0 and C0 are constants; ?Vd is the variation in the focus voltage that it is desired for the system to have; and Bias is the bias that it is desired for the system to have.
